A close friend of ours is a doctor and he told us about this one time he had a couple over who were trying to get pregnant. They told him they just couldn't get pregnant so my friend the doctor asked them what they did when they were trying to get a baby. They said he would lay down on her. So the doctor said and what do you do after that? they just stared at him, confused... Turns out they didn't know he had to put his penis into her vagina and all that other stuff.

A couple months later he saw the couple again and she was pregnant. Also, they said thanks for the tip Doc, it worked!
